DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a nutrition management calculator according to an embodiment will be described with reference to the drawings. FIG. 1 is an external view of a nutrition management calculator according to the embodiment. The nutritional management calculator 2 includes a passport-sized casing that can be carried by a doctor or the like when visiting a patient, and includes an input unit 4 and a display unit 6 on the surface thereof.
[0024]
Further, as shown in FIG. 1, the display unit 6 includes a patient basic information display unit 10 that displays the height, weight, age, and the like of the patient, a calculation result display unit 12 that displays the calculation results, and an infusion or enteral nutrient. It is comprised by the dripping speed display part 14 which displays the dripping speed of. The dropping speed display unit 14 is configured by arranging a plurality of display elements in a line at predetermined intervals along the right edge of the display unit 6.
[0025]
FIG. 2 is a block configuration diagram of the nutrition management calculator 2 according to the embodiment. The nutrition management calculator 2 includes a data control unit 20 that controls processing of data in the nutrition management calculator 2. The data controller 20 includes an input unit 4 for inputting basic patient information including the height and weight of the patient, a basic patient information display unit 10, a calculation result display unit 12, and a drip rate display unit 14. Part 6 is connected. Further, the data control unit 20 stores basic patient information, patient nutrition information, and the like input via the input unit 4, and knee height / length for calculating the estimated height from the knee height of the patient. A data storage unit 22 that stores an estimated height conversion table, a formula for calculating the daily energy consumption of the patient, a standard value used for calculating the nutrition index, a formula for calculating the nutrition index, and the like. It is connected.
[0026]
Here, the patient basic information stored in the data storage unit 22 includes the height, weight, age, sex, activity coefficient, and stress coefficient of the patient. The activity coefficient indicates the state of energy metabolism based on the activity state of the patient because the energy metabolism of the patient changes between the bedridden state and the state of rising in the bed. The stress coefficient (disorder factor) indicates the state of energy metabolism that has increased due to surgery and fever, etc., due to increased energy metabolism due to invasion or fever due to surgery.
[0027]
The knee height / estimated height conversion table stored in the data storage unit 22 is a table for estimating the height from the length of the patient's knee height. For a bedridden patient, a patient with a bent back, and the like, an accurate height cannot be measured. For these patients, the knee height is input instead of the height. When this knee height is input, the estimated height is calculated based on the input knee height by referring to the knee height / estimated height conversion table. Is stored in the data storage unit 22 as the height included in the basic patient information. The data storage unit 22 stores a knee height / estimated height conversion table for Asians.
[0028]
The patient nutrition information stored in the data storage unit 22 includes the values of the triceps skinfold thickness (TSF) and the triceps survivor length (AC). Is included. Further, the standard value used when calculating the nutrition index stored in the data storage unit 22 is the triceps surae fat thickness used when calculating the nutrition index based on the inputted patient nutrition information and This is a standard value for each age group in each gender such as the circumference of the triceps.
[0029]
Next, with reference to the flowchart of FIG. 3, the process which calculates the energy amount (kcal) and dripping speed of the infusion solution or enteral nutrient by the nutrition management calculator which concerns on embodiment is demonstrated.
[0030]
First, the patient's height, weight, age, sex, activity coefficient, and stress coefficient are input as patient basic information via the input unit 4 (step S10). At this time, if it is difficult to measure the height because the patient is bedridden or the back is bent, the length of the knee is input instead of the height. When the length of the knee height is input, the estimated height is calculated from the length of the input knee height with reference to the knee height / estimated height conversion table stored in the data storage unit 22, The calculated estimated height is stored as the patient's height. The patient's sex, height, age, and weight are displayed on the patient basic information display unit 10 from the input patient basic information. When the patient's birth date is input instead of the patient's age, the patient's age is calculated based on the input birth date. Alternatively, the patient's hospitalization date may be input, the patient's hospitalization date may be calculated, and the calculated hospitalization date may be displayed on the calculation result display unit 12.
[0031]
As the activity coefficient, for example, a value of 1.0 is input when the patient is bedridden, and a value of 1.2 is input when the patient is on the bed. In addition, as a stress coefficient, for example, a value in the range of 0.9 to 1.1 is input after a general surgical operation, and when fever is generated, the body temperature is 37 ° C. or more and 1 per 1 ° C. A value obtained by adding 0.12 to is input. It should be noted that the activity coefficient and the stress coefficient are arbitrarily determined by the doctor who performed the patient patrol based on the observation result of the patient by the nurse, the result of examining the patient's condition, etc., and input to the nutrition management calculator 2 It may be. The input patient basic information is stored in the data storage unit 22.
[0032]
Next, based on the basic patient information stored in the data storage unit 22, a total energy amount (daily energy consumption: kcal) required by the patient for one day is calculated (step S11). That is, first, basic energy demand (BEE) (kcal) is calculated based on the sex, age, height, and weight of the patient. This BEE is calculated using a mathematical expression for BEE stored in the data storage unit 22, for example, “655+ (9.6 × weight) + (1.8 × height) − (4. 7 × age) kcal / day (Harris-Benedict formula) ”. Next, the daily energy consumption (kcal) is calculated by multiplying the calculated BEE by the activity coefficient and the stress coefficient included in the basic patient information stored in the data storage unit 22. The calculated daily energy consumption is stored in the data storage unit 22.
[0033]
Next, patient nutrition information including a patient's triceps skinfold fat thickness (TSF) and triceps surae length (AC) is input via the input unit 4. (Step S12). That is, a patient's TSF is measured using a dedicated instrument for measuring TSF, for example, a caliper for measuring subcutaneous fat thickness, and the measurement result is input to the nutrition management calculator 2. At this time, the measurement is usually performed three times, the TSF value at each measurement time is input, and the average value obtained by dividing the total value at each measurement time by the number of measurements is used as the patient TSF as the data storage unit. 22 is stored. Similarly, AC is measured three times, and the value at each measurement time is input. The average value of the measurement values at each measurement time is stored in the data storage unit 22 as the patient's AC.
[0034]
Next, based on the patient nutrition information stored in the data storage unit 22, a nutrition index indicating the nutritional status of the patient is calculated (step S13). Here, first, the upper arm muscular circuit (AMC) is calculated by AMC = AC−π × TSF. Next, a nutrition index is calculated based on the patient nutrition information stored in the data storage unit 22 and the standard values of TSF, AC, and AMC for each age in each gender. That is, a nutrition index indicating the patient's body fat mass (TSF nutrition index) is calculated as “(%) = (patient TSF value) / (standard value of TSF) × 100”, and “(%) = (Patient AC value) / (AC standard value) × 100 ”and“ (%) = (Patient AMC value) / (AMC standard value) × 100 ”nutrition index indicating the amount of muscle protein of the patient (AC nutrition index and AMC nutrition index) are calculated. The calculated nutrition index is stored in the data storage unit 22.
[0035]
Here, based on the value of each nutrition index, it is determined whether or not a nutritional disorder has occurred in the patient. That is, when the value of the nutrition index is 90% or more, it is judged that the nutritional state is normal, when it is 60% or less, it is high, when it is 60-80%, it is medium, and 90% or less. In the case of, it is judged that there is a mild nutritional disorder. Therefore, based on the values of the TSF nutrition index, the AC nutrition index, and the AMC nutrition index, it is determined whether or not the patient has a nutritional disorder.
[0036]
In determining whether or not a nutritional disorder has occurred, the nutritional index of AMC is particularly emphasized. That is, a low AMC nutrition index value means a decrease in the amount of muscle protein. This is because, when the amount of muscle protein is reduced, for example, there is a possibility that delay of wound healing or the like occurs, and the possibility of affecting the recovery of the patient is increased.
[0037]
Next, based on the daily energy consumption (kcal) calculated in step S11 and the nutritional index calculated in step S13, the energy amount (kcal) of the infusion or enteral nutrient for the patient is calculated (step S14). ). That is, the amount of energy (kcal) consumed by the patient per day, and the amount of calories necessary for the patient from the nutritional status of the patient indicated by the nutrition index, that is, the amount of energy (kcal) that needs to be administered to the patient ) Is calculated. The calculated energy amount (kcal) is displayed on the calculation result display unit 12.
[0038]
Further, based on the calculated daily energy consumption (kcal) and the nutritional status of the patient, a doctor or the like selects an infusion solution or enteral nutrient to be administered to the patient. That is, since the amount of liquid (ml) and nutrient composition differ depending on the infusion or enteral nutrient, the patient's age, sex, and so on from among the infusion or enteral nutrient that satisfy the calculated energy (kcal) A doctor or the like will select an appropriate infusion or enteral nutrient that takes into account the pathology.
[0039]
Next, the electrolyte mass (mg) and electrolyte equivalent (mEq / L) based on the weight of the electrolyte of the infusion solution or enteral nutrient administered to the patient are converted (step S15). For example, the weight-based amount (mg) of sodium (Na) contained in the infusion agent or enteral nutrient, the valence and atomic weight of Na are input. Then, an equation for converting the electrolytic mass stored in the data storage unit 22 into an electrolyte equivalent, “electrolyte equivalent (mEq / L) = (amount of Na contained in infusion or enteral nutrient) mg / Based on (Liquid Amount of Infusion or Enteral Nutrient) dL × 10 × (Na Valence) / (Na Atomic Weight) ”, Na electrolytic mass (mg) is converted to electrolyte equivalent (mEq / L) Then, the converted electrolyte equivalent (mEq / L) is stored in the data storage unit 22. Similarly, an electrolyte equivalent (mEq / L) of an electrolyte mass (mg) based on the weight of another electrolyte contained in an infusion solution or enteral nutrition to be administered to a patient, for example, sodium chloride (NaCl). Can be converted to Furthermore, the electrolytic mass (mg) based on the weight of potassium (K), which is a typical electrolyte ion, is converted into an electrolyte equivalent (mEq / L), and the converted electrolyte equivalents (mEq / L) of NaCl and K are converted into the equivalent electrolyte equivalent (mEq / L). The data may be stored in the data storage unit 22. In addition, when each valence and atomic weight of Na, NaCl, and K are stored in the data storage unit 22, the liquid amount (dL) of an infusion or enteral nutrient and Na, NaCl, or K By inputting the amount (mg), it is possible to convert each weight-based electrolytic mass (mg) into an electrolyte equivalent (mEq / L). For example, in a literature such as a paper, when the weight unit is different for each literature, this nutritional management calculator is used to convert the electrolytic mass (mg) and the electrolyte equivalent (mEq / L) to each other. May be.
[0040]
Next, the result of converting the electrolytic mass (mg) to the electrolyte equivalent (mEq / L) in step S15 is displayed on the calculation result display unit 12 (step S16). Here, based on the displayed electrolyte equivalent (mEq / L), the electrolyte equivalent required to be contained in the infusion solution or enteral nutrient solution administered to the patient is confirmed and determined. That is, in the converted electrolyte equivalent (mEq / L), an electrolyte or electrolyte infusion is added to the infusion or enteral nutrient for patients who have insufficient amount of electrolyte to be ingested, Ensure that the patient has the electrolytes they need. In addition, in consideration of the maximum dosage rate without concern for side effects, patient pathology and patient nutrition, etc. with reference to the displayed electrolyte equivalent (mEq / L), infusion or enteral nutrition by doctors and nutritionists The administration time of the agent is determined.
[0041]
When administering an infusion solution or enteral nutrient containing no electrolyte to a patient, other components contained in the infusion agent or enteral nutrient, for example, the amount of amino acids, the amount of sugar, the solution The dose time is determined by a doctor, a dietitian, etc. in consideration of the amount, energy amount and patient's desire.
[0042]
Next, the input unit 4 is used to input the liquid amount (ml) of the infusion solution or enteral nutrient to be administered to the patient and the administration time determined by the doctor or the like based on the electrolytic mass calculated in step S15. (Step S17). Note that the liquid solution amount (ml) and administration time of the input infusion solution or enteral nutrient are stored in the data storage unit 22.
[0043]
Next, the dropping rate of the infusion solution or enteral nutrient is calculated based on the input amount (ml) of the infusion solution or enteral nutrient and the administration time (step S18). Here, when calculating the dropping speed, first, whether the patient is an adult or a child is selected. That is, since the thickness of the drip tube used when administering an infusion or enteral nutrient varies depending on whether it is an adult or a child, the number of drops of drip varies. Therefore, after selecting an adult or a child, the drip rate (drops / min) when an infusion or enteral nutrient is administered to the patient is calculated. The calculated dropping speed is stored in the data storage unit 22.
[0044]
Next, the dropping rate calculated in step S18 is displayed on the dropping rate display unit 14 (step S19). That is, by alternately blinking the plurality of display elements constituting the dropping rate display unit 14, the actual dropping rate of the infusion or enteral nutrient is displayed so that it can be visually grasped.
[0045]
FIG. 4 is a diagram for explaining a display state of the dropping speed in the dropping speed display unit 14. As shown in FIG. 4, the dropping rate display unit 14 is configured by arranging three display elements, for example, LEDs (Light Emitting Diodes) at equal intervals in the vertical direction on the right edge of the display unit 6.
